Abstract

A sealing arrangement for placement between two components which have a planar contact surface, in particular two housing parts of a pump. The sealing arrangement has an elongate, flexible sealing element whose end region has a termination element thereon, which can carry out a sealing function. The sealing element and the termination element have an overlap region in the end region of the sealing element and thus form a first continuous sealing edge. The sealing edge is maintained also for a displacement of the end region of the sealing element in the direction of the start region within the overlap region. The termination element moreover has a first curvature. The curvature and the sealing element are configured so that the sealing element contacts the termination element along the curvature in a pressure-free state.

Dependent claims

A sealing arrangement for placement between two components which have a planar contact surface, comprising:

a first elongate flexible sealing element which comprises a first start region and a first end region;
and
a first termination element which is configured to carry out a sealing function;
wherein the first sealing element and the first termination element are configured so that they have a first overlap region in the first end region of the first sealing element and thus form a first continuous sealing edge,
wherein the first sealing element is displaceable relative to the first termination element so that the first sealing edge is maintained during a displacement of the first end region of the first sealing element in the direction of the first start region within the first overlap region;
and
wherein the first termination element has a first curvature and the first sealing element contacts the first termination element along the first curvature in a pressure-free state.
